IMPROVEMENT IN MACHiNES FOR CUTTING VENEERS.

Specification forming part of Letters Patent No. 131,994, datedSeptember 3, 1872.

declare the following description and accompanying drawing aresufficient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovements without further invention or experiment.

My invention relates to certain improvements in machines for cutting orslicing off thin veneers or strips from a previously-prepared block ofwood; and it consists, principally, of a device for automaticallyfeeding said block to the cutting-knife without requiring the attentionof the operator.

In order to more fully illustrate and explain my invention reference ishad to the accompanying drawing forming a part of this specification, inwhich- Figure 1 is a side sectional elevation. Fig. 2 is a fiont view.

v A is the table or bench upon which the block to be cut isplaced, and Bis the knife,

which is secured in a frame, 0, said frame being arranged to move up anddown between two guides or posts, D D. In the usual working of theseknives the block is held in place by dogs at each end, and the frameupon which it is secured is moved forward, so as to feed the block tothe knife by an ordinary pawl and ratchet operated by the drop of theknife. Usually I shall construct the top of the table or bench A so thatit can be adjusted to any desired angle in either direction, so as topermit the block to be presented to the knife in any desired position.This I have not shown. E represents the block which This block restsupon the table A, and, in order to steady it, I employ at each side ofthe table a slotted plate, f, the inner edge of which is turned up, soas to present a vertical side strip, the two opposite strips formingaguide, between which the block moves. These plates f can be adjusted toand from each other in order to accommodate different-size blocks. Tothe rear edge of the table I secure a vertical standard,

G, by means of a horizontal foot-piece or timber, h. The ends of thisfoot-piece are slotted longitudinally, andbolts pass through the slotsinto the table, so that the vertical post can be shifted from side toside in order to keep it opposite the center of the block E. Thestandard Gis slotted nearly its entire length, and has secured in thisslot one end of a horizontal drop bar, I, at the proper height to allowits opposite end to rest upon the upper side of the block just in therear of the knife. J is a timber, the upper end of which passes looselythrough a hole or opening in the upper end of the frame, while its lowerend is slotted so as to permit it to straddle the horizontal dropbar I.A roller, K, is secured in this slot, so that the-roller will rest onthe drop-bar while the weight of the timber bears upon the roller. Therear end of the drop-bar I, as well as'the roller K, may be'adjustcd upand down, as required by the thickness of the block E. Below the bar I apresse'r-foot, l, is secured to the lower end of the timber J, so thatit will rest upon the block E, as shown. A cord, m, has one end securedto a yoke, a, on the timber J,

just above the drop-bar I, and passes forward over a pulley, 0, in theforward end of the drop-bar; thence back over a pulley, p, in the rearend of the drop-bar where a weight, Q, is attached to it. Thus it willbe seen that the weight is continually pulling the lower end of thetimber J forward, and causing it to press the block against the knife.In order to relieve this pressure when desired, another cord, 4", or, ifdesired, an extension of the same cord, is carried from the yoke '12 upover a pulley, s, at the upper end of this standard G, and then down toa shaft, t, to which'it is secured. This shaft can be turned by a crank,so as to withdraw the lower end of the timber J, and be held in thisposition by a ratchet, 'v,

and pawl "12, while the block is being replaced or adjusted. To gage thethickness of the veneer or slice to be cut, I secure to the outside ofthe frame in which the knife is held, and below the knife, a transversetimber, w. This timber is held in'place by screws, so that it can bemoved to or from the knife, according to the thickness which it isdesired to cut the veneers or slices. Usually I shall place verticalstrips 00 ac a short distance apart onv the inside of the timber w,against which the block E can bear, the spaces between them serving tocarry away or release any chips which may be detached from the block;but these strips can be dispensed with, as desired. Now, when the knifeis lifted, the weight Q, causes the lower end of the timber J toimmediately press forward the block E against the timber 20, which givesthe desired thickness of the veneer or slice. The descending knife thensplits off the veneer in the usual way.

By this means I greatly improve the present veneer-cutting machinerendering it automatically feeding, and capable of doing a greateramount of work in a more perfect manner and with a less amount oftrouble.

Having thus described my invention what Witnesses:
